Regarding the Dual mode on ADC - Can the channels be coupled arbitrarily?

Hi all,

Thanks in advance for your time, appreciate it!!

My doubt is over the microcontroller STM32H743ZI. It has 3 ADC modules integrated. As far as I understand, each module has a Sample and Hold, thus ADCs 1 and 2 can be coupled in order to work in DUAL mode (ADC1 Master, ADC2 Slave), sampling simultaneously; a necessary feature if two signals want to be measured at the exact same time for applications such as three-phase power converters.

My question is: Can I couple for dual mode two arbitrary channels of each ADC?

For example:

-Dual pack 1: ADC1INP3 & ADC2INP4

-Dual pack 2: ADC1INP17 & ADC2INP14

Thank you very much!
